Abstract
L'invention concerne un procédé (110) d'évaluation de l'adéquation de conditions d'éclairage permettant de détecter un analyte dans un échantillon à l'aide d'une caméra (112) d'un dispositif mobile (114). Le procédé comprend les étapes suivantes consistant à : a) (117) capturer au moins une première image d'au moins une bande d'essai (116), la bande d'essai (116) étant adaptée pour détecter l'analyte dans l'échantillon, la bande d'essai (116) comportant au moins un champ de test (118) comprenant au moins une substance chimique de test permettant de mettre en œuvre une réaction de détection optique en présence de l'analyte, une source d'éclairement (120) du dispositif mobile (114) étant éteinte lors de la capture de la première image; b) (122) capturer au moins une seconde image de la bande d'essai (116), la source d'éclairement (120) du dispositif mobile (114) étant allumée lors de la capture de la seconde image; c) (124) comparer les première et seconde images capturées aux étapes a) (117) et b) (122), ce qui permet de déterminer une différence de conditions d'éclairage entre la première image et la seconde image; et d) (126) déduire au moins des informations d'adéquation à partir de la comparaison de l'étape c) (124), les informations d'adéquation comprenant des informations associées à une adéquation des conditions d'éclairage à une détection d'analyte.
